Abstract
In this paper we propose a very-low-voltage (VLV) testing technique for CMOS logic ICs. Voltage dependence of CMOS logic circuit operation in the presence of resistive shorts and hot carrier damage is studied. It is shown that at certain much-lower-than-normal power supply voltage, weak CMOS logic ICs due to the presence of these flaws can be forced to malfunction while truly good ICs continue to function. Very-low-voltage testing also detects pattern dependent faults caused by resistive shorts. Because of its simplicity and because there is no overhead associated with it, very-low-voltage testing can easily be applied to chips and circuit boards as a production test, field test, or failure diagnosis techniqueKeywords
